    I found that the whole JDK suffers the “UnknownHostException” error: the only way I can connect to other hosts is to use -Dsun.net.spi.nameservice.provider.1=dns,sun in the command line; I added this to the MyEclipse link and now I can download updates.

    The UML error still remains.

    Can anybody confirm this is being investigated?

    p.dario,
    We still havent been able to replicate it in our test environment. A “NoClassDefFoundError” is 99% of the time a configuration issue. However either we do not know enough about your configuration to duplicate it our side or there is some mis-understanding of information you provided. Could you please post all the information we request in [URL=http://www.myeclipseide.com/PNphpBB2+file-viewtopic-t-393.html]Posting Guidelines[/URL].
    Thanks,
    Kapil

    Hallo,

    I had the same problem with the UML-Repository,
    after inserting my Hostname with the externel address to my /etc/hosts file everythings works fine.

    Maybe that helps..

    Olaf,
    Thanks for sharing this with other users. Just to confirm, you solved the same “NoClassDefFound” error i.e.

    
 com.genuitec.eclipse.uml.wizard.NewUMLModelFileWizardPage.getNewFile(): java.lang.NoClassDefFoundError

    by inserting a resolution entry for localhost in the hosts file?

    Kapil,

    I inserted the Computername with the externel IP:

    10.60.33.122 Frodo

    Under the localhost definition

    MESSAGE Exception in com.genuitec.eclipse.uml.wizard.NewUMLModelFileWizardPage.getNewFile(): java.lang.NoClassDefFoundError

    I had the same problem when trying to create my first model repository.
    When I look at the console output in the terminal where I started eclipse I noticed:

    …

    And that was exactly the case.
    I could not ping my own hostname for some reason.
    I changed /etc/hosts accordingly and sure enough ……. it works.
    I’ve got my first repository.

    Best,

    Could a personal firewall stop UML Repository creation??

    Hi ,

    Very simple:
    I have a Ubuntu 7.04.

    Replaced the line below in /etc/hosts:
    127.0.0.1 localhost myhost.myhostdomain

    To:

    127.0.0.1 myhost

    Where myhost is the name defined in the file /etc/hostname.

    Thanks!
